## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 747-100, -200B, -200C, -200F, and -300 series airplanes delivered in or modified into the stretched upper deck configuration. This action requires a one-time inspection to detect chafing between certain engine thrust control cables and certain cable penetration holes, and follow-on actions, if necessary. This action is necessary to prevent chafing and failure of engine thrust control cables, which could result in a severe asymmetric thrust condition during landing, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
